STOVEI SPECIFICATION forming part of Letters Patent N0. 767,834, datedAugust 16, 1904.

Application filed November 7, 1903. Serial No. 180,206. (No model) T allwhom it may concern.:

Be it known that I, FRANK J. PIOCH, a citizen of the United States, anda resident of Provo City, in the county of Utah and State of Utah, haveinvented new and useful Improvements in Stoves, of which the followingis a full, clear, and exact description.

My invention relates to stoves, my more particular object being toproduce an efiicient, reliable, and economical stove having a downdraft.l

My present invention constitutes certain improvements over my otherinvention de-v scribed in my'application, Serial No. 145,312, iiledFebruary 27, 1903.

Reference is to be had to the accompanying drawings, forming a part ofthis speciiication, in which similar characters ofA reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical central section of a stove embodying my inventionupon the line 1 1 of Fig. 2. Fig. 2 is a horizontal section upon theline 2 2 of Fig. 1 looking in the direction of the arrow., and Fig. 3 isa horizontal section upon the line 3 3 of Fig. 1 looking in thedirection of the arrow.

An outer shell l is provided with a false bottom 2, having a centralopening 3, these parts being partially encircled by a substantiallyconical base 4. This base is provided with a central opening 5 and witha manuallyoperated slide 6. The stove rests upon legs 7 in the usualmanner, and these legs may be of any desired form. A ring 8 supports theskirt 36, as hereinafter described.

The Ventilating-pipes are shown at 9 and pass through the top 10 of thestove and also through the conical base 4. The stove is provided withdoors 11, 12, 13, and 14, which may be of any desired form and providedwith knobs 16 17 18. These doors form no part of my present invention,and I do not limit myself to the use of doors of any particular kind. Adraft-tube 19 is provided for allowing egress of the gases of combustionand is provided with a damper 20, controlled by means of a handle 21,whereby any desired degree of curtailment of the gases may be effected.

The {ire-pot is shown at 22 and at its botbustion from the lire-pot arefree to pass downward between the stays 28 and also between theVentilating-pipes 9 in the direction indicated by the arrows. Alift-plate 30 is provided inthebottom of the inner shell 29 and isprovided with an aperture 31 to be eugaged by a lifter. A flue 32 leadsupwardly from the base of the stove at one side of the shell 1, and uponthe neck 33 at the top of said passage a stovepipe may be secured in theusual manner.

The inner shell 29 rests in cup-joints 34, which afford a secure andstrong fastening. The apertures 35 in the bottom plate 35a, on whichplate the lift-plate 30 rests, are for the purpose of affording room forany hinges and fastening devices which may be employed upon the doors,and the annular space 22" encircling the fire-pot is for the purpose offeeding hot air into the top of the fire-pot and at the same time toprotect the shell 29 against excessive heat.

The bottom 4 is encircled by a hoop-like member 8, integrally mountedupon a fiange at the cup-joints 34, as shown more particularly inFig. 1. The hoop-like member 8 and the flange just mentioned present incrosssection the appearance of a T. The purpose of this arrangement isto space the hoop-like member 8 slightly from the outer shell 1, so asto allow for mounting the ornamental skirt 3G, which is provided withapertures 37 to allow the passage of air through the skirt. The spacebetween the hoop-like member 8 and the outer shell 1 also serves to makeroom for any bolts or other fastenings which may be used in holding thestructure together. Below the flange on which the hoop-like member 8 isformed is another hoop 43, connected IOO with the legs 7 and serving asan annular support, whereby a considerable portion of the weight of thestove is sustained. A foot-rest 41 is mounted upon brackets 89, eachbracket having an anchor 40 passing radially through the lower end ofthe skirt 86, as shown more particularly in Fig. 1. 'Ihe skirt 86 isprovided at its upper portion with an annular flange 42, bendingdownwardly and inwardly, as shown. This Harige 42 serves to hook overthe hoop-like member 8, so that the skirt 86 depends therefrom, and thussupports the footrest 41. A hoop 44 is also attached to the legs 7,as'shown in Fig. 1.

The warm air passing' around the conical portion 4 of the stove spreadsradially outward through the aperture 37 and is thus used for warmingthe feet of persons engaging the foot-rest 41.

It will be observed that the hoops 48 and 44 are connected with the legs7 of the stove, and thus form a foot upon which the weight of the stoverests, whereas the skirt 36 hangs over the hoop-like member 8. By thisarrangement no bolts need be used in connecting the stove with itsfooting. By means of the skirt 36 a comely and attractive appearance isgiven to the entire lower portion of the stove independently of theeffect of the skirt 36 in warming' the feet of persons while the stoveis in use.

While I preferably employ the skirt and footing above described, I donot limit myself to this particular construction.

It will be noted that with the several parts of the stove as above shownand described the inside work of the stove is supported so as to haveconsiderable strength.

The object of the annular space 22b between the fire-pot 22 and theinner shell 29 is to allow air to circulate around the lire-pot andprevent injury to the same from the intense heat. The air in this space22" in thus absorbing heat from the lire-pot and preventing injurythereto becomes itself heated to a very high temperature and passesupwardly through the narrow openings 22c above the space 22", curlinginwardly and downwardly, so as to pass beneath the hot-blast ringradially toward the center of the fire-pot. In other words, the hot airsimply flows in a curved path inwardly over the edge of the fire-pot andpasses radially toward the center of the same in immediate contact withthe burning fuel. In doing this the hot air crowds very closely to themouth of the fire-pot, and this fact, together with its close proximityto the fuel, causes it to become heated to a higher temperature. rIheair thus heated having passed downwardly into the fire-pot consumes all,or at least a great part, of the smoke and gases which may be arising'from the fuel, and this feature is in the line of economy of fuel aswell as of thorough heating.

The hot-blast ring 27 or safety-grate, as

it is sometimes called, answers four different purposes, to wit: y

First. It directs the heated air from the space 22" down over the roughfire, so as to burn the gas and smoke, as above stated. Unless this stepwere accomplished not only would the smoke and gas be wasted, but theymight become a nuisance after making their escape.

Second. The hot-blast ring serves as a covering or roof over the spaceencircling the upper edge of the fire-pot. In doing this it preventsashes and small pieces of coal from falling into the space 22h,encircling the lire-pot.

Third. The radial members 28 to some extent prevent pieces of coal. fedto the fire from falling into the space encircling the inner shell 29.

Fourth. The radial members 28 serve as braces, and thereby strengthenthe stove.

It will be noted that air passing upward through the passage 32 is drawnfrom a point directly in the center of the base. There is,

therefore, no .so-called short.run, the distance between the severalparts being so proportioned that the stove is heated all around. Inother words, the structure of the stove is such that the flames and hotgases are forced to travel routes of such proportionate length 'as toclearly distribute their heat and prevent one part of the stove frombecoming exclusively hot as compared with another part.

The feed-door opening of the stove is made very large. The reason forthisis that the lire-pot 22, if broken or damaged, may be lifted bodilythrough the feed-door opening and taken out of the stove, so as to bereplaced by another. In order to facilitate the removal of the fire-pot,I do not limit myself to a firepot made in a single piece; but I mayemploy fire-pots of other kinds, if desired.

rIhe operation of my device is as follows: A lire having been made inthe lire-pot 22, the gases of combustion pass over the end of thefire-pot and immediately between the stays 28, passing downward andcirculating around the Ventilating-pipes 9, heating the same thoroughly.The gases of combustion next pass into the space 4 and are thence drawnupwardthrough the flue 82, this flue being formed by the partitions 2828, the inner shell 29, and the outer shell 1, as will be seen from Fig.3. It will be noted that the updraftiue thus formed is entirely withinthe stove, being encircled by the outer shell 1. The air within theVentilating-pipes 9 being heated passes upward, and cold air isconstantly drawn in the bottom ends of these ventilating-pipes.

I/Vhile I preferably employ the ventilatortubes 9, I wish it to beunderstood that I do not limit myself to this construction.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a stove, the combination of a footing,

and a skirt of annular form encircling said footing and dependingtherefrom, said skirt being provided with means for permitting hot airto pass therethrough, and a foot-rest disposed adjacent to said skirt.

2. In a stove, the combination of inner and outer shells, means forproducing a revertible draft between said inner and outer shells, asubstantially conical member connected with said outer shell anddisposed at the lower end thereof, and means for compelling a draft fromthe center of said substantially conical member to a point of dischargefor the smoke and gases.

3. In a stove, the combination of an outer shell and an inner shell, aplurality of partitions each connected with said inner shell and saidouter shell, two of said partitions being spaced asunder and forming anupdraft-flue intermediate of said inner and said outer shells, alire-pot disposed within said inner shell,the arrangement being suchthat the gases of combustion from said fire-pot are free to passdownwardly intermediate of said shells, and then to pass upwardlythrough said flue, and

a plurality of ventilator-tubes located inter-v mediate of said shellsand thus exposed to a revertible draft.

4. In a stove, the combination of a footing provided at its top with anannular member,

an ornamental skirt provided with perforations and with an orifice forengaging said annular member, said skirt depending from said annularmember, and a foot rest disposed within the path of air passing throughsaid perforations.

' 5. In a stove, the combination of stove-legs, annular membersconnecting the same together and forming therewith a footing, 'a shellmounted upon said footing, a skirt connected with said footing anddepending therefrom, said skirt being provided with perforations, and afoot-rest disposed within the path of air passing through saidperforations.

6. In a stove, the combination of a body portion, a footingforsupporting the same, a metallic skirt of annular form provided withmeans for permitting air to pass therethrough, and also providedadjacent to one of its edges with an annular flange for encircling saidfooting, land -a foot-rest connected with the lower portion of saidskirt and supported thereby.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
